(Gold) - The Walking Robot
walking robot shifts its center of gravity to walk and turns by sliding
its feet in opposite directions.
Hardware The Toddler is a high quality robot CNC-machined
from aluminum and brass. The aluminum parts are brushed, anodized,
acid-etched to make the perfect finish (put the legs on a buffing wheel
for a silver shine!). The package includes body parts, legs, ankles,
control linkages, screws/nuts/standoffs, etc. Requires 2-3 hours to
assemble and tune. The aluminum parts have holes, slots and configurable
mounting angles for your own customization. A complete parts listing is
available in Appendix A of the Advanced Robotics text.
Electronics The Toddler is controlled by a surface
mounted BASIC Stamp 2 module. Four infrared sensors and receivers, LEDs,
servos for tilt and stride, resistors/capacitors, speaker,
photoresistors complete the control system.
4.8V Mini STD Servo
Documentation Includes the 155-page Advanced Robotics
text in the Stamps in Class style and the 351-page BASIC Stamp Manual.

Education Walking robots have mechanical and software
interdependencies that require in-depth examples and explanation. The
Advanced Robotics text is a 155-page introduction to the Toddler's basic
movements. Students using the Toddler will learn advanced embedded
programming with BASIC, efficient code development, sensor feedback, and
general control. Because of the number of possible movements (34) we
consider the Toddler to be appropriate for those aged 14 and above.
